To all whom it may concern:

Be it known that if, lfiinr ns'r S. Kmar- LAND, a citizen of the UnitedStates, residing at Maiden, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Weighing Device, of whichthe following is a specification.

It is the object of this invention to provide a weighing device adaptedto control accurately, and to cut oil at predetermined weight, grain andthe like, as the same flows from ,1 hopper into a receptacle.

Another object of the invention is to provide an electrically controlledmember adapted to be manipulated manually to open the hopper, the saidmember being operated electrically, when a predetermined amount of grainhas passed fromthe hopper, to close the hopper.

Anoth r object of the invention is to provide weight indicatingmechanism of novel and improved form.

Another objector the invention is to provide novel means for opening andclosing the hopper.

The drawings show typical embodiments merely, and it is to be understoodthat changes, properly falling within the scope of what is claimed, maybe made, without dcparting from the spirit of the invention.

In the drawings, Figure 1 is a fragmental side elevation, parts beingbroken away and shown in section; 2 is a fraginental side elevation, thedevice being viewed at right angles to the showing of 1 and parts beingbroken away and shown in section; and Fig. 3 is a transverse section ofthe device along the line AB ofhig. :2

The supporting frame upon which the structureis mounted may be of anyform; in the present instance diverging legs 1 are shown, united intheir intermediate portions by cross braces 2, and likewise united,adjacent their upper ends by frame members 3. Oppositcly disposed framemembers 3 are provided with duplicate mechanisms,

one of which will be described specifically it being understood that thedescription applies with equal propriety to the other of saidmechanisms. Levers i aret'ulcrumcd at 5, intermediate their ends uponone of the frame members 3. Suitable connecting devices 6, unitepivotally the remote ends of the levers 4 with the upper portion of areceiver, the same being shown in the form of a conical spout 7.

the levers i are connected w'lh he inter mediate portion of a scale beam9 by a link and eye mechanism 8.

The scale beam 9, hereinafter referred to as the movable weightindicating member, is J-shaped, to extend partially around the receiver7. Adjacent its ends, the scale beam 9 is pivotally connected, as at 12,with the receiver 7. ii' cights 10 are slidable upon the scale beam 9 toone side of the connections S and i2 and other weights ii are slid-ableupon the some beam to the other side of the connections 8 and i2 andadjacent the ends of the scale beam. he weights it serve to indicate theweight of the contents of the receiver 7 while the members 11 may bemanipulated to actcounier to the weights 10, thereby to compensate inthe well known manner, for the falling grain which is between the bottomof the receiver 7 and the closure members 21 when the latter cometogether to cut' oil' the grain. Thus, if the weights 10' are set at 100pounds, and the weights 11 are set at zero, a tr'al charge may be runinto the receiver T. This trial charge when removed from the receiver 7and weighed, will weigh more than 100 pounds, say 107 pounds,the sevenpounds representing the grain which was falling at the time the beam 9tilted to close the parts 21. if the weights 11 are then set to theseven pound mark, the sub sequent charges will weigh 100 pounds even.The lower end the receiver 7 is provided with a ring .15 in which aslide 16 is mounted to shut off the outflow from the receiver, tics 14-serving to steady the receiver 7 between the logs of one of thesupporting frames.

Into a receiver, constructed as above pointcd out, or in any othersuitable manner, a. hopper i8 positioned to discharge, the hopper beingsustained in the door 17 of the grain bin. Secured to the hopper 18 is aplatform if), the hopper and the -ilatt'orin being referred tohereinafter under the general designation of a receptacle. Pivotcdat 90-to the hopper 18, adjacenttheir upper are a pair of coiipcrating closuremembers 21. adapted to'swing beneath the hopper 18, to close the same.Lugs 2'2 outstand from the closure members 21 at one end thereof, andthese lugs are adapted to register slidably in the slots 23, located inthe diverging arms of a Y-shaped, resilient latch In the Those closuremembers 21 are platform 19 there is an opening 25 adapted to receive theshank of the latch lever and in this opening the latch lever is mountedfor vertical. reciprocation. "The intermediate portion of a lever 26 isfulcrumed upon a standard 27 rising from the platform 19, one end of thelever 26 being pivotally united with the upper end of he latch 24. Forthe manipulation of the lever 26, a cord 35 or the like may be connectedtherewith. Upon the outer face of the latch 2% there is a pro jection36, adapted to engage with the upper face of the platform 19 adjacentthe opening 25 in which the latch moves. Disposed upon the platform 19between the latch 24 and the hopper 18, is an electromagnet 29. Wires 30extend from the electromagnet to binding posts 31 located upon theplatform 19. From these binding posts 31, other wires 32 extend tofingers 33, pivotally supported above the scale beam 9, and located uponthe receiver 7 adjacent the upper end thereof. Interposed in theelectrical conductors uniting the fingers 33 with themagnet 29, is abattery 3a. This battery 34 may be supported in any desired manner, andlocated at any desired distance from the mechanism hereinbeforedescribed.

, The operation of the device is as follows; presupposing that the partsare positioned as shown in Fig. 1. The slidable member 10 is adjustedupon the, scale beam 9 to indicate the desired weight. The cord 35is'then drawn upon, "tilting the lever 26, and causing the latch 24: tomove. upwardly through the opening 25 in the platform 19. This upwardmovement of the latch 2 1 will cause the lugs 22 to slide in the slots23 of the latch, the closure members 21 being thus swung apart touncover the lower end of the hopper 18. As thelatch '24 is thus lifted,the projection 36 thereon will pass upwardly through the opening 25 inthe platform 19, and engage the platform, holding the closure members 21in an open position. From the hopper 18 the grain will flow downwardlyinto the receiver 7 resting upon the slide 16 therein. The grain willaccumulate in the receiver until the weight of the grain therein issuflicient to tilt the scale beam 9 upwardly, raising the weight 10. Asthe scale beam'thus moves upwardly, the beam will contactwith thepivotally mounted fingers 32 thus com leting the circuitthrough thewires 30 an 32 energizing the electromagnet 29. The freenpper-Jend ofthelatch 24 will be drawn toward the hopper 18, alinin the projection 36vertically with the opening 35, whereupon the closure members 21 willswing into the closed osition shown in ig. 1, thus cutting o "the flowof grain from the hopper 18 into the 1;8- -ceiver 7. At this point itmay profitably be stated that the lever 26.is loosely mounted in thestandard 2? so that the latch 21- may move sufiiciently to disengage theprojection 36 from the platform 19.
